Comte Gustave Auguste Bonnin de la Bonninière de Beaumont (16 February 1802 in Beaumont-la-Chartre, Sarthe – 30 March 1866, Tours) was a French magistrate, prison reformer, and travel companion to the famed philosopher and politician Alexis de Tocqueville. While he was very successful in his lifetime, he is often overlooked and his name is synonymous with Tocqueville's achievements.
Beaumont was born on 6 February 1802 in Beaumont-la-Chartre, Sarthe to the count Jules de Beaumont and Rose Préau de la Baraudière. He was the youngest of 4 children. Beaumont spent his early years in the chateau de La Borde in his birthplace. Like Tocqueville, Beaumont came from nobility; he was a descendant of the Bonin de la Bonnière family.
